Lust - (or lechery) is usually thought of as involving obsessive or excessive thoughts or desires of a sexual nature. Unfulfilled lusts sometimes lead to sexual or sociological compulsions and/or transgressions including (but obviously not limited to) sexual addiction, adultery, bestiality, rape, and incest.
Gluttony -Derived from the Latin gluttire, meaning to gulp down or swallow, gluttony is the over-indulgence and over-consumption of anything to the point of waste.
Avarice - (or greed, covetousness) is, like lust and gluttony, a sin of excess. However, greed (as seen by the church) is applied to the acquisition of wealth in particular.
Sloth - (laziness) More than other sins, the definition of sloth has changed considerably since its original inclusion among the seven deadly sins. In fact it was first called the sin of sadness or despair. It had been in the early years of Christianity characterized by what modern writers would now describe as melancholy: apathy, depression, and joylessness — the last being viewed as being a refusal to enjoy the goodness of God and the world he created.
Wrath - (or anger) may be described as inordinate and uncontrolled feelings of hatred and anger. These feelings can manifest as vehement denial of the truth, both to others and in the form of self-denial, impatience with the procedure of law, and the desire to seek revenge outside of the workings of the justice system (such as engaging in vigilantism) and generally wishing to do evil or harm to others.
Envy - (jealousy) Like greed, envy is characterized by an insatiable desire; they differ, however, for two main reasons. First, greed is largely associated with material goods, whereas envy may apply more generally. Second, those who commit the sin of envy desire something that someone else has which they perceive themselves as lacking.
Vanity - In almost every list pride ( or hubris or pride) is considered the original and most serious of the seven deadly sins, and indeed the ultimate source from which the others arise. It is identified as a desire to be more important or attractive than others, failing to give compliments to others though they may be deserving of them, and excessive love of self (especially holding self out of proper position toward God).
